Abu Bakr

First Muslim Caliph and a companion of Muhammad

Abū Bakr ibn Abu Quhhafa (c. October573–23 August634 CE / 13 AH) was a companion of and the first Muslim ruler after Muhammad (632–634). Sunnis regard him as his rightful successor (caliph) and the first of four righteous Caliphs (Rashidun). The Shi'a believe he violated Muhammad's direct orders and orchestrated a coup d'état. Scholarly consensus lists him as the first Muslim Caliph.
